COMPOSITE SEMICONDUCTOR DEVICE, LED HEAD THAT EMPLOYS THE COMPOSITE SEMICONDUCTOR DEVICE, AND IMAGE FORMING APPARATUS THAT EMPLOYS THE LED HEAD

摘要

A composite semiconductor device includes a substrate, a plurality of circuits, a semiconductor thin film layer, and a dummy pattern. The circuits are formed on the substrate, and include one or more wiring layers. The semiconductor thin film layer includes semiconductor elements and is disposed on an uppermost surface of the one or more layers. A dummy pattern is formed in an area where the one or more wiring layers are absent. A spin-coated layer is formed between the semiconductor thin film layer and the wiring layers. The spin-coated layer may be formed of an organic material or an oxide material.
